Contents of the conduits in the cycle

• 1a – control: start/restart
• 2a – response: initial
• 1b – control: repeat/stop
• 2b – response: additional
• 3 – information/data: preferred language
• 4 – information/data: translation (optional)
• 5 – information/data: image or sound (optional)
• 1c – control: repeat/stop

Sequencing of the conduits in the cycle

• 1a, 2a, 1b, 2b, and 1c use a format that is not distinctly analog or digital, but is for human recognition and sending
• 1b and 2b are repeated back and forth several times for initialization, authentication, calibration, and synchronization
• 5 and 1c can be repeated back and forth several times for scan lines or layers in an image, or channels in a sound

Conduit types

• B – begin
• E – control, response, and information/data: contains commonly recognized languages and standards
• V – information/data: contains a mix of analog and digital information in commonly recognized languages and simplified formats
• F – information/data: contains a mix of analog and digital information in the full preferred format
• L – control: contains an interactive language
• I – response: contains an interactive language
• J – information/data: contains the full preferred language
